RESUMEN

BACKGROUND: Safe blood is essential for the care of patients with life-threatening anemia and hemorrhage. Low blood donation rates, inefficient testing procedures, and other supply chain disruptions in blood administration affect patients in low-resource settings across Sub-Saharan countries, including Kenya. Most efforts to improve access to transfusion have been unidimensional, usually focusing on only point along the blood system continuum, and have excluded community stakeholders from early stages of intervention development. Context-appropriate interventions to improve the availability of safe blood at the point of use in low-resource settings are of paramount importance. Thus, this protocol proposes a multifaceted approach to characterize the Kenyan blood supply chain through quantitative and qualitative analyses as well as an industrial engineering approach. METHODS: This study will use a mixed-methods approach in addition to engineering process mapping, modeling and simulation of blood availability in Kenya. It will be guided by a multidimensional three-by-three-by-three matrix: three socioeconomic settings, three components of the blood system continuum, and three levels of urgency of blood transfusion. Qualitative data collection includes one-on-one interviews and focus group discussions with stakeholders across the continuum to characterize ground-level deficits and potential policy, systems, and environment (PSE) interventions. Prospectively-collected quantitative data will be used to estimate blood collection and transfusion of blood. We will create a process map of the blood system continuum to model the response to PSE changes proposed by stakeholders. Lastly, we will identify those PSE changes that may have the greatest impact on blood transfusion availability, accounting for differences across socioeconomic settings and levels of urgency. DISCUSSION: Identifying and prioritizing community-driven interventions to improve blood supply in low-resource settings are of utmost importance. Varied constraints in blood collection, processing, delivery, and use make each socioeconomic setting unique. Using a multifaceted approach to understand the Kenyan blood supply and model the response to stakeholder-proposed PSE changes may lead to identification of contextually appropriate intervention targets to meet the transfusion needs of the population.

RESUMEN

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality in Kenya. The aim of this study was to measure quality and timeliness of care for PPH in a sample of deliveries in referral hospitals in Kenya. We conducted direct observations of 907 vaginal deliveries in three Kenyan hospitals from October 2018 through February 2019, observing the care women received from admission for labor and delivery through hospital discharge. We identified cases of "suspected PPH", defined as cases in which providers indicated suspicion of and/or took an action to manage abnormal bleeding. We measured adherence to World Health Organization and Kenyan guidelines for PPH risk assessment, prevention, identification, and management and the timeliness of care in each domain. The rate of suspected PPH among the observed vaginal deliveries was 9% (95% Confidence Interval: 7% - 11%). Health care providers followed all guidelines for PPH risk assessment in 7% (5% - 10%) of observed deliveries and all guidelines for PPH prevention in 4% (3% - 6%) of observed deliveries. Lowest adherence was observed for taking vital signs and for timely administration of a prophylactic uterotonic. Providers did not follow guidelines for postpartum monitoring in any of the observed deliveries. When suspected PPH occurred, providers performed all recommended actions in 23% (6% - 40%) of cases. Many of the critical actions for suspected PPH were performed in a timely manner, but, in some cases, substantial delays were observed. In conclusion, we found significant gaps in the quality of risk assessment, prevention, identification, and management of PPH after vaginal deliveries in referral hospitals in Kenya. Efforts to reduce maternal morbidity and mortality from PPH should emphasize improvements in the quality of care, with a particular focus on postpartum monitoring and timely emergency response.

RESUMEN

OBJECTIVE: Using a qualitative design this study aimed to (1) explore the experience of people living with osteoarthritis (OA), (2) gain an understanding of their navigation of the health system and, (3) explore their opinions on the role of exercise and joint replacement surgery for the management of OA. METHODS: Purposive sampling was used to recruit 26 participants with knee OA, aged 45 years and over, from Tasmania, Australia. Semi-structured interviews were audio-recorded, transcribed, coded, and thematically analysed to document participant understanding and experience of OA and their opinions on the role of exercise and surgery in managing OA. RESULTS: Of the 26 participants, 80% (n = 21) were female with a mean age of 66 years. The main theme identified was that individuals with knee OA were navigating a maze of OA treatments. Three related subthemes were that participants: (i) perceived their general practitioner did not have an ongoing role in their OA care, (ii) self-directed their management and, (iii) sampled from a 'smorgasbord' of treatment options, including low-value care options. Two other major themes were: the role of exercise for OA management, and surgery as a last resort. CONCLUSION: Our findings suggest that OA patients may not be choosing consistent, high-value care for their OA. This highlights the importance of an evidence-based multi-disciplinary approach to guide patients to self-manage their OA and support their navigation of the health system. Reducing emphasis on the pathway to surgery and streamlining access to conservative management strategies may assist people to receive high-value care.

RESUMEN

BACKGROUND: The supply of blood in many low- and middle-income nations in Sub-Saharan Africa (SSA) does not meet the patient care needs. Lack and delay of blood transfusion cause harm to patients and slow the rate of progress in other parts of the health system. Recognizing the power of implementation science, the BLOODSAFE Program was initiated which supports three SSA research study teams and one data coordinating center (DCC) with the goal to improve access to safe blood transfusion in SSA. STUDY DESIGN AND METHODS: The study team in Ghana is focusing on studying and decreasing iron deficiency in blood donors and evaluating social engagement of blood donors through different approaches. The study team in Kenya is building a "vein to vein" workflow model to elucidate and devise strategies to overcome barriers to blood donation and improve infrastructural components of blood product production and use. The Malawi team is studying the infectious disease ramifications of blood donation as well as blood donor retention strategies aimed at blood donors who commence their donation career in secondary schools. RESULTS AND DISCUSSION: Together the project teams and the DCC work as a consortium to support each other through a shared study protocol that will study donor motivations, outcomes, and adverse events across all three countries. The BLOODSAFE Program has the potential to lead to generalizable improvement approaches for increasing access to safe blood in SSA as well as mentoring and building the research capacity and careers of many investigators.

RESUMEN

Hemorrhage is responsible for at least 40% of deaths after trauma and 27% of maternal deaths worldwide. Patients with hemorrhagic shock require attentive critical care and transfusion of blood products. Access to a safe and affordable blood supply is critical to providing safe surgical care. Traumatic injury, obstetric hemorrhage, and upper gastrointestinal bleed are the main causes of severe bleeding requiring transfusion. This article discusses the presentation and management of these causes across the world and provides a brief overview of the current challenges in maintaining a global blood supply.

RESUMEN

There is a critical shortage of blood available for transfusion in many low- and middle-income countries. The consequences of this scarcity are dire, resulting in uncounted morbidity and mortality from trauma, obstetric hemorrhage, and pediatric anemias, among numerous other conditions. The process of collecting blood from a donor to administering it to a patient involves many facets from donor availability to blood processing to blood delivery. Each step faces particular challenges in low- and middle-income countries. Optimizing existing strategies and introducing new approaches will be imperative to ensure a safe and sufficient blood supply worldwide.

RESUMEN

Many adverse pregnancy outcomes are the result of placental disorders. It has been difficult to decipher the root cause of many of these disorders due to an overlap in identifiable placental pathology and pregnancy outcomes. The reason for this confusion may be related to the lack of an appropriate control placenta. An ideal control placenta that is not related to adverse pregnancy outcomes is rare. We propose our pooled database at the Global Pregnancy Collaboration (CoLab) could be a solution for researchers.

RESUMEN

BACKGROUND: Human migration is a worldwide phenomenon that receives considerable attention from the media and healthcare authorities alike. A significant proportion of children seen at public sector health facilities in South Africa (SA) are immigrants, and gaps have previously been noted in their healthcare provision. The objective of the study was to describe the characteristics and differences between the immigrant and SA children admitted to Kalafong Provincial Tertiary Hospital (KPTH), a large public sector hospital in the urban Gauteng Province of SA. METHODS AND FINDINGS: A cross-sectional study was conducted over a 4-month period during 2016 to 2017. Information was obtained through a structured questionnaire and health record review. The enrolled study participants included 508 children divided into 2 groups, namely 271 general paediatric patients and 237 neonates. Twenty-five percent of children in the neonatal group and 22.5% in the general paediatric group were immigrants. The parents/caregivers of the immigrant group had a lower educational level (p < 0.0001 neonatal and paediatric), lower income (neonatal p < 0.001; paediatric p = 0.024), difficulty communicating in English (p < 0.001 neonatal and paediatric), and were more likely residing in informal settlements (neonatal p = 0.001; paediatric p = 0.007) compared to the SA group. In the neonatal group, there was no difference in the number of antenatal care (ANC) visits, type of delivery, gestational age, and birth weight. In the general paediatric group, there was no difference in immunisation and vitamin A supplementation coverage, but when comparing growth, the immigrant group had more malnutrition compared to the SA group (p = 0.029 for wasting). There was no difference in the prevalence of maternal human immunodeficiency virus (HIV) infection, with equally good prevention of mother-to-child transmission (PMTCT) coverage. There was also no difference in reported difficulties by immigrants in terms of access to healthcare (neonatal p = 0.379; paediatric p = 0.246), although a large proportion (10%) of the neonates of immigrant mothers were born outside a medical facility. CONCLUSIONS: Although there were health-related differences between immigrant and SA children accessing in-hospital care, these were fewer than expected. Differences were found in parental educational level and socioeconomic factors, but these did not significantly affect ANC attendance, delivery outcomes, immunisation coverage, HIV prevalence, or PMTCT coverage. The immigrant population should be viewed as a high-risk group, with potential problems including suboptimal child growth. Health workers should advocate for all children in the community they are serving and promote tolerance, respect, and equal healthcare access.

RESUMEN

Objective: Using a qualitative design this study aimed to 1) explore the attitudes towards and understanding of osteoarthritis (OA) held by Tasmanian general practitioners (GPs) and orthopaedic surgeons, 2) gain a deeper understanding of conservative and surgical management and 3) identify key barriers and challenges. Design: Purposive sampling was used to recruit 17 â€‹GPs and 10 surgeons from Tasmania, Australia. Semi-structured interviews were audio-recorded, transcribed, coded, and thematically analysed to document understanding of OA, management and treatment decision making. Results: GPs and surgeons had a shared understanding of the cause and management of OA which aligned well with evidence-based best practice. Most GPs acknowledged that severity of disease on an X-Ray does not correlate well with symptoms, although some GPs reported always using imaging to support their diagnosis. Conservative management was highly supported by all interviewees, focussing on exercise and/or physiotherapy. Key treatment barriers included managing poor patient understanding of OA, unrealistic expectations for treatment, lack of patient motivation and scepticism towards exercise, and cost and accessibility of conservative treatment options. Surgery was considered a suitable option when conservative management options had been exhausted. Conclusion: This study uniquely interviewed GPs and surgeons from the same population, capturing two crucial areas of OA management. Some key barriers to treatment were identified and options for improving treatment include creating opportunities for increased patient education about OA, enhanced accessibility to OA conservative management programs along with improved reimbursement models supporting conservative management as first-line OA treatment.

RESUMEN

STUDY OBJECTIVE: To establish face and construct validity for a novel variation of American College of Obstetrics and Gynecology "Flowerpot Model" for transvaginal hysterectomy (TVH) surgical simulation with improved vesicovaginal dissection during surgical education simulation. DESIGN: Cross-sectional face and construct validation study using the "Flowerpot Model." The vesicovaginal dissection plane was modified to include additional felt and balloon materials to simulate the bladder. SETTING: Single academic center. PARTICIPANTS: Fourteen residents and fellows, postgraduate year (PGY) 2 to 6, subdivided into junior (n = 8) with ≤10 prior TVH surgeries and senior groups (n = 6) with >10 prior TVH surgeries performed. INTERVENTIONS: All subjects watched a brief introductory video and then were filmed simulating a TVH. MEASUREMENTS AND MAIN RESULTS: For face validity, subjects completed an anatomic checklist and pre/post simulation satisfaction survey. For construct validation, 2 independent, blinded expert surgeons (M.A. and J.M.) graded films using the Global Rating Scale of Operative Performance (GRS). Primary outcome was mean GRS between groups. The junior group consisted of PGY 2 to 3 with ≤ 10 prior TVH, median 7.5 (interquartile range [IQR] 6.75) and senior group PGY 3 to 6 with >10 TVH, median 19 (IQR 10) (p <.01). Subjects were "satisfied" or "very satisfied" with bladder and anterior peritoneal fold simulation (92%) and found vesicovaginal dissection "realistic" (100%). GRS score was significantly different between groups (juniors, 19.5 [IQR 5] vs seniors, 28.5 [IQR 8.5]; p = .048). Intergrader correlation was high (ρ = 0.87, p <.01). Surgeon volume of prior TVH was not significantly correlated to average GRS score, ρ = 0.49 (p = .10). The model improved comfort and confidence scores in the junior group more than senior group (p = .04), but senior group still had higher post simulation confidence scores than the junior group (p = .02). CONCLUSION: Face and construct validity with the modified Flowerpot Model was demonstrated. This low fidelity model is capable of simulation of a TVH with a novel vesicovaginal dissection. Prior surgical experience was not correlated to GRS score or time to procedure completion.

RESUMEN

OBJECTIVE: To quantify the consequences of a total ban on indoor tanning for short-term regulatory enforcement, for consumers, and the longer-term health economic effects. METHODS: Instances of illegal solarium prosecutions and tanning bed confiscations in the state of Victoria (population 7 million) were obtained from government surveillance records. Consumer interest for indoor tanning and spray/fake tanning were assessed using Google Trends' Search Volume Index (range 0 to maximum 100). Long-term health economic effects were estimated using a Markov cohort model. RESULTS: The Victorian Government completed 13 prosecutions and confiscated 39 illegal tanning units. Consumer interest for indoor tanning reduced to less than one quarter of pre-regulation seasonal peaks (Search Volume Index 12/48) while spray tanning interest remained high (70-88). For young Australians over their remaining lives, banning commercial indoor tanning is expected to avert 31,009 melanomas (-3.7%), avert 468,249 keratinocyte cancers (-3.6%) and save over AU$64 (US$47) million in healthcare costs and produce over AU$516 (US$375) million in productivity gains. CONCLUSIONS: Three years after the nationwide ban, regulation enforcement activities have decreased, and consumers have adopted substitute tanning methods.

RESUMEN

INTRODUCTION: Two-thirds of maternal deaths and 40% of intrapartum-related neonatal deaths are thought to be preventable through emergency obstetric and newborn care (EmOC&NC). The effectiveness of 'skills and drills' training of maternity staff in EmOC&NC was evaluated. METHODS: Implementation research using a stepped wedge cluster randomised trial including 127 of 129 healthcare facilities (HCFs) across the 11 districts in South Africa with the highest maternal mortality. The sequence in which all districts received EmOC&NC training was randomised but could not be blinded. The timing of training resulted in 10 districts providing data before and 10 providing data after EmOC&NC training. Primary outcome measures derived for HCFs are as follows: stillbirth rate (SBR), early neonatal death (ENND) rate, institutional maternal mortality ratio (iMMR) and direct obstetric case fatality rate (CFR), number of complications recognised and managed and CFR by complication. RESULTS: At baseline, median SBR (per 1000 births) and ENND rate (per 1000 live births) were 9 (IQR 0-28) and 0 (IQR 0-9). No significant changes following training in EmOC&NC were detected for any of the stated outcomes: SBR (adjusted incidence rate ratio (aIRR) 0.97, 95% CI 0.91 to 1.05), iMMR (aIRR 1.23, 95% CI 0.80 to 1.90), ENND rate (aIRR 1.04, 95% CI 0.92 to 1.17) and direct obstetric CFR (aIRR 1.15, 95% CI 0.66 to 2.02). The number of women who were recognised to need and received EmOC was significantly increased overall (aIRR 1.14, 95% CI 1.02 to 1.27), for haemorrhage (aIRR 1.31, 95% CI 1.13 to 1.52) and for postpartum sepsis (aIRR 1.86, 95% CI 1.17 to 2.95). CONCLUSION: Following EmOC&NC training, healthcare providers are more able to recognise and manage complications at time of birth. This trial did not provide evidence that the intervention was effective in reducing adverse clinical outcomes, but demonstrates randomised evaluations are feasible in implementation research. TRIAL REGISTRATION NUMBER: ISRCTN11224105.

RESUMEN

Ethnic/racial minorities are under-represented in blood donor populations in most developed countries. This is of particular concern where minorities differ from a country's majority population in terms of blood or tissue typing, especially where type matching is required for effective management of rare disorders such as sickle-cell disease that require multiple transfusions. This systematic review assessed the effectiveness of interventions to increase blood donation among ethnic/racial minority populations in developed countries. We searched MEDLINE, EMBASE, CINAHL, and ProQuest on 20 March 2017 with no date restrictions and supplemented this with searches on Google Scholar, blood collection agency websites, reference lists of included studies, and a forward search of citations of included studies. We included intervention studies designed to increase recruitment and/or retention of adult, ethnic/racial minority blood donors in developed countries. The review identified eight studies reported in nine publications. Six were conducted in the USA with African Americans. Four studies reported on multifaceted, community-based interventions; three reported on one-off information and educational video interventions, presented face-to-face, or delivered via post or e-mail. The level of evidence for efficacy was low, and the majority of studies were assessed as having some risk of bias related to one or more methodological issues. All eight studies reported positive outcomes in blood donation and/or intention to donate. Seven trials found that the intervention increased presentation for donation, and three found an increase in the percentage of new donors from the ethnic minority targeted. The review findings demonstrate that it is possible to design and implement effective interventions to motivate individuals from ethnic/racial minority groups to donate blood. One-off interventions may be as effective as multifaceted, community-based interventions. There was insufficient evidence to recommend particular interventions, and future research should empirically assess alternative interventions using robust study designs.

RESUMEN

The objective was to assess the feasibility and safety of the ̳Every Second Matters for Emergency and Essential Surgery - Ketamine' (ESM-Ketamine) package in support of obstetric and gynecologic emergency and essential surgery when no anesthetist is available. A consecutive case series was conducted in twelve hospitals across five severely resource-limited counties in Kenya. 530 women underwent obstetric or gynecological operative procedures supported by non-anesthetist clinicians using the ESM-Ketamine package between November 1, 2013 and September 30, 2017. Main outcomes included reasons for ESM-Ketamine activations and ketamine-related adverse events. There were two (0.4%) prolonged (>30 seconds) oxygen desaturations below 92%. Brief oxygen desaturations (<30 seconds) below 92% occurred in 15 (2.8%) cases and 113 (21.3%) were administered diazepam to treat hallucinations or agitation. There were no ketamine-related deaths or injuries. The ESM- Ketamine package appears feasible and safe for use in support of obstetric and gynecologic surgeries when no anesthetist is available.

RESUMEN

BACKGROUND: Postpartum hemorrhage is the most common cause of maternal deaths worldwide, the majority of which occur in low-resource settings. Uterine balloon tamponade (UBT) is an effective method of addressing uncontrolled postpartum hemorrhage (PPH) from uterine atony; however, UBT devices are often not affordable. We report on three novel uses of an ultra-low-cost condom uterine balloon tamponade (ESM-UBT) device. CASES: ESM-UBT devices were used in innovative ways to arrest severe uncontrolled pregnancy-related hemorrhage among three women in India and Tanzania. The first had sustained deep vaginal lacerations, the second a cervical pregnancy, and the third a complete molar pregnancy. CONCLUSION: The ESM-UBT device may be useful for control of obstetric hemorrhage caused by complex vaginal tears as well as cervical and molar pregnancies.

RESUMEN

OBJECTIVES: To evaluate quality of life (QoL) parameters among women categorized with a maternal near-miss during pregnancy. METHODS: The present prospective cohort study was conducted at a tertiary referral hospital in South Africa between April 1, 2013, and March 31, 2016. Patients who experienced maternal near-miss events were included and patients with uncomplicated low-risk pregnancies were enrolled as a control group. Various parameters were assessed using a WHO QoL questionnaire. RESULTS: The maternal near-miss and uncomplicated low-risk pregnancy (control) groups comprised 95 and 51 women. The maternal near-miss group scored lower than the control group in all four domains of the questionnaire (P<0.001). Overall, 42 (82%) women in the control group and 41 (43%) women in the maternal near-miss group desired future fertility (P<0.001). Women in the maternal near-miss group who had experienced perinatal loss scored lower in the physical health and well-being (P=0.009), psychological health and well-being (P=0.007), and environment (P=0.031) domains compared with women in the maternal near-miss group who experienced a live delivery. Nonetheless, QoL scores among women in the maternal near-miss group who had experienced perinatal loss remained lower than those reported by women in the control group (P<0.001). CONCLUSION: A maternal near-miss event during pregnancy was associated with reduced QoL, especially among women who had experienced perinatal loss.

RESUMEN

CONTEXT: Skin cancer is a preventable and commonly diagnosed cancer in the U.S. Excessive ultraviolet radiation exposure is a known cause of skin cancer. This article presents updated results of two types of interventions evaluated in a previously published Community Guide systematic review: multicomponent community-wide interventions and mass media interventions when used alone. EVIDENCE ACQUISITION: Studies assessing multicomponent community-wide and mass media interventions to prevent skin cancer by reducing ultraviolet radiation exposure were evaluated using Community Guide systematic review methods. Relevant studies published between 1966 and 2013 were included and analyzed for this review. EVIDENCE SYNTHESIS: Seven studies evaluating the effectiveness of multicomponent community-wide interventions showed a median increase in sunscreen use of 10.8 (interquartile interval=7.3, 23.2) percentage points, a small decrease in ultraviolet radiation exposure, a decrease in indoor tanning device use of 4.0 (95% CI=2.5, 5.5) percentage points, and mixed results for other protective behaviors. Four studies evaluating the effectiveness of mass media interventions found that they generally led to improved ultraviolet protection behaviors among children and adults. CONCLUSIONS: The available evidence showed that multicomponent community-wide interventions are effective in reducing the deleterious effects of ultraviolet radiation exposure by increasing sunscreen use. There was, however, insufficient evidence to determine the effectiveness of mass media interventions alone in reducing ultraviolet radiation exposure and increasing ultraviolet protection behaviors, indicating a continuing need for more research in this field to improve assessment of effectiveness.

RESUMEN

BACKGROUND: Globally 166 000 women die annually as a result of obstetric haemorrhage. More than 50% of these deaths occur in sub-Saharan Africa. Uterine atony is the commonest cause of severe postpartum haemorrhage (PPH). Bleeding at or after caesarean section (CS) is responsible for >30% of maternal deaths due to obstetric haemorrhage in South Africa (SA). OBJECTIVE: To compare oxytocin alone with oxytocin + ergometrine in terms of primary prophylaxis for PPH at the time of CS. METHODS: This was a double-blind randomised controlled interventional study comparing oxytocin with oxytocin + ergometrine administered during CS. Patients were randomised to receive oxytocin alone intravenously as a bolus or oxytocin + ergometrine intramuscularly, with the placebo being an injection of sterile water. The study population consisted of women undergoing CS at Kalafong Provincial Tertiary Hospital in Atteridgeville, Gauteng, SA. RESULTS: Five hundred and forty women were randomised and data for 416 women, of whom 214 received oxytocin and 202 oxytocin + ergometrine, were available for analysis. In the oxytocin group 19 women (8.9%) required blood transfusion, compared with seven (3.5%) in the oxytocin + ergometrine group (p=0.01; relative risk = 2.78; 95% confidence interval 1.21 - 6.4). There were no statistically significant differences in the mean estimated visual and mean calculated blood loss. CONCLUSIONS: The overall need for blood transfusion was significantly reduced by about two-thirds in women receiving the oxytocin + ergometrine combination. Consideration should be given to using oxytocin + ergometrine for prophylaxis of PPH at CS.
